I just purchased the new 27" imac and have been messing around with files coming off of an external hard drive that is connected through the network. All in all it seems like my old MacBook transfers files much faster from the external hard drive to the MacBook than my Imac from the external hard drive to the Imac. I tested it a few times and the results are: Transferring the same exact file 112.4MB size. The MacBook transfered the file in 1min and 27 seconds The iMac transfered the the same file in 8 in and 42 seconds I would assume the iMac should be A LOT faster than an old MacBook. Could I have some settings messed up in the iMac? The imac is the base line for 27 inch (3.2 GHz Intel core i3, 4GB 1333 MHz DDR3 The MacBook is (2.16 GHz Intel Core Duo 1 GB 667 MHz DDR2 Any help would be much appreciated. I really hope the imac isn't slower than my old MacBook.
